What is Italian futurism?

Futurism was an artistic and intellectual movement of the early to mid-twentieth century. Its development in Italy is associated with broader European modernist currents, including cubism.
The futurists embraced technological advances, locating within them the possibilities for positive growth and change that they found lacking in turn-of-the-century Italy. In 1909, Filippo Tommaso Marinetti published a manifesto in the Parisian Figaro magazine. Advocating not only abandoning but actually destroying the obsolete past—including its repositories in museums and libraries—futurists embraced everything that was novel in all art genres, from music to fashion.
Notable futurist painters and sculpture include Umberto Boccioni, Luigi Russolo, and Giacomo Balla, who issued their own manifesto in 1910. Despite similarities to Cubist works shown in 1912, they maintained their movement originated independently.
Patriotism impelled their support for Italy in World War I and, more problematically, for fascism and Mussolini from the 1920s onward. Even as a new generation of futurists arose, the political associations with the dark side of nationalism and, finally, Axis defeat, both brought an end to the movement and tainted its legacy.
